Capital Pear Tree - Knowledgebase Question

We are continuing our search for a suitable replacement or substitute for the current "Red Spire" species of Bradford Pear tree planted along our main street. A new species of Bradford pear tree has been recommended for its reduced height and size. I wonder if you could provide us information on the "capital" species of Bradford Pear Tree (info on height/branch width/disease resistance, etc).

Pyrus calleryana, called the Capital Callery Pear, was patented in 1972. The tree has a strong central leader, strong branching, and a pyramidal form, maturing into a round headed tree 30-35 feet in height. Because the trees have wide angle crotches, they're less susceptible to breakage during freezing rainstorms or from the weight of winter snow. Capital Pear trees are growing in Holland, Canada, Michigan, New York, on the grounds of the Capital in Washington DC, in California, Florida, and Ohio (where they are the street tree of choice). The trees show excellent insect and disease resistance, grow fast, and provide beautiful fall color.
